The equation of the line is of the form y = 3x + c where c is a constant. The point (4,9) is on the line, so substituting x=4, y=9 in the equation, 9 = 3*4 + c = 12 + c so c = -3 So the equation of the line is y = 3x - 3
if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form
Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).
The slope-intercept form of an equation is: y = mx + b Just copy down this equation, then replace "m" with the slope, and "b" with the y-intercept.
The slope of x and the y intercept as for example in the straight line equation of y = 2x+3 the slope is 2 and the y intercept is 3
y = 2x + 1.
You can write it either in standard form (ax + by = c) or in slope-intercept form (y = mx + b)
y=mx+b y0=mx0+b 5=3*2+b b=5-5=0 y=3x+0
The equation of a line with an undefined slope is x = a.
The equation of the line is of the form y = 3x + c where c is a constant. The point (4,9) is on the line, so substituting x=4, y=9 in the equation, 9 = 3*4 + c = 12 + c so c = -3 So the equation of the line is y = 3x - 3
you say undefined

if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form
Write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (1, 1).
Any vertical line has an undefined slope. The equation of the vertical line is x = a where the x-intercept is a.
y= slope + y-intercept
