If the slope is equal to 4, and you have point (-4,3), what is the y-intercept of the line?

b = 19

Step-by-step explanation:

Since the slope of the line and a point is given, we can plug these into the point-slope formula and solve for the slope-intercept equation.

Point-slope formula : y - y = m(x -x)

m = 4

( x,y) = (-4,3)

y-3 = 4(x- -4)

y-3 = 4x + 16

y = 4x + 19

The y-intercept formula shows us the slope and y-intercept. In the equation, y = mx + b, b is the y-intercept. So for this line the y-intercept is 19.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
