Answer:

[tex]y = 5x - 3[/tex]

Step-by-step explanation:

Given

[tex]Slope, m = 5[/tex]

[tex](x_1,y_1) = (2,7)[/tex]

Required

Determine the line equation

Using slope intercept form, the line equation can be calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

Substitute values for m, x1 and y1. The equation becomes

[tex]y - 7=5(x - 2)[/tex]

Open Bracket

[tex]y-7 = 5x - 10[/tex]

Add 7 to both sides

[tex]y-7+7 = 5x - 10+7[/tex]

[tex]y = 5x - 3[/tex]

Hence, the line equation is: [tex]y = 5x - 3[/tex]
