Which linear equation would produce a y-int. of (0,-7) and a slope of 5?

`\Large\maltese\underline{\textsf{B. This problem has been solved!}}`

Take the second co-ordinate of the point (0,-7), this is your y-intercept.

Next, just put it into y=mx+b in the place of b.

`\bf{y=mx-7}` | now put in the slope, 5

`\bf{y=5x-7}`

`\cline{1-2}`

`\bf{Result:}`

`\bf{=y=5x-7}`

`\LARGE\boxed{\bf{aesthetic\\ot1\theta l}}`

Answer 2

a.) y = 5x - 7

Step-by-step explanation:

Equation:

`\sf y - y_1 = m(x - x_1)`

insert values

`\sf y - (-7) = 5(x - 0)`

simplify

`\sf y + 7 = 5x`

rewrite

`\sf y = 5x - 7`
