Find the slope of y equals 8x-2?

What slope is 7x plus 5y equals 35?
-7/5 For equations in Standard Form (Ax + By = C), slope equals -A/B. Or you could put the equation in Slope-Intercept form (y = mx + b) by solving for y and then finding the slope (m).
What is the slope-intercept from of the equation of a line with slope 5 and y-intercept -8?

How do you find the slope of an equation?
How to find slope if you are given the equation of a line in slope-intercept form:Slope intercept form is y = mx + b. m is the slope.For example, the slope of the line y = 3x + 7 is 3. (3 is m in the equation y = mx + b.) Another example, the slope of the line y = (-5/4)x - 4 is -5/4.If the line is in the form y = a number, then the slope is 0. For example, the slope of the line y = 3 is 0.If the line is int the form x = a number, then the slope is undefined. For example, the slope of the line x = 5 is undefined.How to find slope if you are given the equation of a line in point-slope form:Point slope form is y - y1 = m(x - x1). m is the slope.For example, the slope of the line y-6 = 2(x-7) is 2. Another example, the slope of the line y-5 = (3/2)(x+4) is 3/2.How to find the slope if you are given the equation of a line in standard form:Standard form is ax + by = c.One way to find the slope if a line in standard form is to convert it to slope-intercept form (y=mx+b).Here is an example using the line 3x + 8y = 283x + 8y = 28First move the x to the other side by subtracting 3x from each side:8y = 28 - 3xNext, divide each side by 8 (all three terms must be divided by 8):y = 28/8 - (3/8)xAfter simplifying the fractions, the formula is y = 7/2 - (3/8)xSlope-intercept form is y = mx + b, so the terms on the left side of the equation need to be rearranged for it to truly be in slope-intercept form:y = -(3/8)x + 7/2Be sure to keep the negative signs in front of their terms! (if you have any negative sings, there will be times when you won't.)The equation of the line 3x + 8y = 28 in slope-intercept form isy = -(3/8)x + 7/2. The slope of this line is -3/8 (see How to find slope if you are given the equation of a line in slope-intercept form, above).Another, faster way is to use the formula -a/b. The slope of the line 3x + 8y = 28 is -3/8. (Remember, this only works for standard form (ax + by = c).)
