Answer:
y = 4x-7
Step-by-step explanation:
slope = difference of y-values / difference of x-values
= (9-5) / (4-3)
= 4/1
select a point to use in the slope-intercept form of a line: y = mx + b where 'm' is the slope and 'b' is the y-intercept
(3,5)
5 = 4(3) + b
5 = 12 + b
-7 = b
slope is 4 and y-intercept is -7
y = 4x-7
