Answer:
y = 3x+4
Explanation:
slope formula is changes of y over the changes of x
m is slope in y = mx+b.
Substitute the coordinate points in.
Since we know the slope, we rewrite by substituting m = 3 in the slope-intercept form.
Then we either substitute one of given coordinate points to find the value of b. I will substitute (1,7) in the equation.
Then rewrite the equation from y = 3x+b by substituting the value of b.
