To find the x-intercept for 5x - 4y = 18, plug in a 0 for the y value and solve for x.
5x - 4(0) = 18
5x = 18
x = 18/5 or 3.6
The line will hit the x-axis at (3.6,0)

What is the y-intercept for 5x-4y equals 18?
Transform the equation into slope-intercept form: y = mx + b. The intercept is b. 5x - 4y = 18 -4y = 18 - 5x 4y = 5x - 18 y = 5x/4 - 18/4 so the y-intercept is -18/4 or -4.5
What is the ordered pair of 5x equals 4y equals -20?
5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair
What is the slope of the line -5x - 4y equals 6?
-5x-4y = 6 -4y = 5x+6 Divide all terms by -4 y = -1.25x-1.5 Slope = -1.25 and intercept = -1.5
What is the x-intercept and y-intercept of 5x subtract 4y equals 1?
y-intercept: -1/4 x-intercept: 1/5 5x-4y=1 -4y=-5x+1 y=5/4x+1/-4 5x-4y=1 5x=4y+1 x=4/5y+1/5
How do you solve 3X plus 2Y equals 16 and 5X plus 3Y-18 equals 4Y by substitution?
First collect like terms in the second equation: 5x - 18 = 4y - 3y ie y = 5x - 18 Substitute this for the term in y in the first equation, getting 3x + 2(5x - 18) = 16 ie 3x + 10x - 36 = 16 ie 13x = 16 + 36 so x = 4 and y = 5 x 4 - 18 ie 2.
What is the y-intercept for 5x-4y equals 18?
Transform the equation into slope-intercept form: y = mx + b. The intercept is b. 5x - 4y = 18 -4y = 18 - 5x 4y = 5x - 18 y = 5x/4 - 18/4 so the y-intercept is -18/4 or -4.5
What is the y-intercept for this linear equation 5x - 4y equals 18?
-4y=-5x+18 is the same equation. Now divide both sides by -4 and you find the y intercept is -18/4 or -9/2
Write an equation of a line parallel to 5x-4y equals 8?
5x-4y=8
Slope of 5x plus 4y equals 20?
5x + 4y = 204y = -5x + 20y = (-5/4)x + 5
-2x-4y plus 5x-7y equals?
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
What is the ordered pair of 5x equals 4y equals -20?
5x=4y=-20 x=-4 y=-5 (-4,-5) is the ordered pair
What is the slope of the equation 5x plus 4y equals negative 3?
5x+4y = -3 4y = -5x-3 y = -5/4 x - 3 Slope is -5/4.
What is the slope of the line -5x - 4y equals 6?
-5x-4y = 6 -4y = 5x+6 Divide all terms by -4 y = -1.25x-1.5 Slope = -1.25 and intercept = -1.5
5x-4y equals -41 4x plus 35 equals?
5x - 4y = -41 => 5x = 4y - 41 => x = (4y - 41)/5 Then 4x + 35 = 4*[(4y - 41)/5] + 35 = 16y/5 - 164/5 + 35 = 16y/5 -11/5 or (16y - 11)/5
What is the x-intercept and y-intercept of 5x subtract 4y equals 1?
y-intercept: -1/4 x-intercept: 1/5 5x-4y=1 -4y=-5x+1 y=5/4x+1/-4 5x-4y=1 5x=4y+1 x=4/5y+1/5
5x - y equals 27 5x plus 4y equals 42?
27 + y = 42 - 4y so 5y = 15 making y = 3 and x = 6
What is the slope and y intercept of the equation 5x plus 4y equals 20?
5x+4y = 20 4y = -5x+20 y = -5/4x+5 Therefore: slope is -5/4 and intercept is 5
