- Slope-Intercept Form: y = mx + b, with m = slope and (0,b) as the y-intercept.
So starting with the y-intercept, the easiest method to find it is to convert this standard form equation to slope-intercept form. Firstly, add 5x to both sides:

Next, divide both sides by -4 and your slope-intercept form is 
Looking at this slope-intercept form, <u>the y-intercept is (0, -5/2).</u>
Now to find the x-intercept, just set the y-variable to zero and solve:

<u>Our x-intercept is (-2,0).</u>
Answer:
25x ²−49y ²
Step-by-step explanation:
We need to find product of (5x+7)(5x−7y)
By using identity (a+b)(a−b)=a −b ²
We have a=5x,b=7y
Thus (5x+7y)(5x−7y)=(5x) ²−(7y)

Answer:
(-8,-1)
Step-by-step explanation:
B because 13 x 13 = 169
3.14 x 169 = 530.7
Yes it is a function Bc the x values each have a unique y value.
