Answer:

y = 2x + 5

Step-by-step explanation:

The standard equation of a line in slope-intercept form is expressed as:

y = mx+c

m is the slope

c is the inercept

Given the coordinates (-4, -3) and (1,7)

Get the slope

m = y2-y1/x2-x1

m = 7-(-3)/1-(-4)

m = 7+3/1+4

m = 10/5

m = 2

Slope is 2

Get the y intercept c

Substitute any of the point say (1, 7) and slope m = 2 into the expression y = mx+c as shown;

7 = 2(1) + c

7 = 2+c

c = 7-2

c = 5

Hence the y-intercept is 5

Get the required equation

Recall that y = mx+c

y = 2x + 5

Hence the values that will go into the blank spaces are 2 and 5
